History

Food history Nicolas Appert

Nicolas Appert.

Napoleon acclimated to say that the army marches on its stomach. The basic of a soldier was absolute meat, dried aliment and whatever beginning aliment he could aces up as he confused along. The wars had an aftereffect on the accepted bodies as able-bodied and aliment shortages were rampant. The government acerb believed that the action of both the army and the noncombatant citizenry would be abundantly bigger if alone a bigger adjustment of attention aliment would be developed. To this effect, in 1795 the French aggressive offered an accolade of 12,000 francs to a being who could appear up with a applied solution.

After abounding abstracts Appert assured that air was the account of aliment accident and he approved to abolish as abundant of it as possible. Neither canteen jars nor metal cans were about yet and Nicolas Appert had to use bottles. Those actuality attenuated were ill ill-fitted to ample with aliment so Nicolas advised his own advanced aperture bottles, which looked like canteen bottles that were acclimated for circadian milk deliveries afterwards on.
